Background

With the popularization and application of steel structure buildings, the steel structure field construction technology and environment are more and more emphasized. Welding is one of the most important links in steel structure field construction, and the quality of welding quality directly influences the overall quality of steel structure construction. The welding quality of the field construction is influenced by various factors such as the flatness of the groove, the plate thickness, the welding current, the technical level of a welder, humidity, wind power and the like. In the relevant specifications of welding, requirements are also made on the temperature, humidity and wind power at the time of welding. Therefore, temporary wind prevention measures are taken around the welding operation in site construction so as to reduce the influence of wind on the welding quality. In the welding of steel column field interfaces, the traditional windproof measures comprise a very fine welding protective cage or a very fine platform and a very crude temporary wind-shielding cloth. Although the former has the advantages of standard manufacture and good wind shielding effect, the former needs to be disassembled and assembled by a crane and has higher cost, and the latter has the advantages of low cost and easy erection, but is not firm and airtight generally and has poor wind shielding effect. For a construction unit, a high-cost temporary facility is not always willing to be invested, and a low-cost temporary facility is not easy to control the welding quality, so that a windproof device which is low in cost, easy to erect, good in windproof effect and capable of being recycled is needed to assist in improving the welding quality.
